BOTTOM-OPENING CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Original application filed July 3, 1908, Serial No. 441,797. Divided andthis application filed March 5, 1910. Serial No. 547,389.

To all whom it may concern:

Be it known that I, ARTHUR J. BAZELEY, a citizen of the United States,and a resident of Cleveland, Cuyahoga county, Ohio, have invented a newand useful Improvement in Bottom-Opening Car-Couplers, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings. forming part of this specification, inwh1ch Figure 1 is a front elevation of my improved coupler in position,showing the bottom-operating connections; Fig. 2 is a verticallongitudinal section of the coupler; Fig. 3 is a view similar to Fig. 1,but showing a modified form of operating connections; Fig. 4 is a viewsimilar to Fig. 2,

showing the modified form of Fig. 3; and Fig. 5 is a cross sectional.View showing a lock of either form.

This application'forms a divisional part of my application Serial No.441,797, filed July 3rd, 1908, for a car coupler.

In the drawings, referring to the form of Figs. 1, 2 and 5, 2 representsthe coupler body, and 3 the usual swinging knuckle, this being of theusual M. C. B. type. The part 4 is the locking and opening piece, whichis preferably of angle form, as shown in Fig. 5, having the locking head4 and the member 4*, which fits back of the tail of the knuckle, and isadapted to open the same. The lockin and opening piece is provided witha notchor recess 4", adapted to en age a bearing 5 on the coupler, whenthe lifting piece is lifted and tipped thereon to swing the knuckleopen. The portion 4 of the locking and opening piece is also providedwith an upwardly projecting hook or eye 6, which is preferably formed onor cast integral therewith, and within this hook or eye fits the bentarm portion 7 of a lifting rod 8, projecting upwardly through a hole inthe floor of the coupler. This lifting rod is formed with a verticalslot 9, within which is loosely pivoted a swinging link member 10, by apin or rivet 18* passing through holes in the bottom portion of the rod.At

the lower forwardly projecting end of the' link member 10 is an eye 11,for receiving the end of the uncoupling rod 12, this eye being forwardof the pivotal connection of the member 10, so that when the knuckle isin locked position, the free upper end of the member 10 will moveforward by gravity under the floor of the coupler. in front of the holefor the rod, as shown in Fig. 2. This link member, therefore, acts as astop to prevent the accidental creeping or jumping of the look. When theuncoupling rod is actuated to lift the lifting rod, the first action isto tilt the member 10 rearwardly, so as to free its upper end fromengagement with the coupler and bring its upper end portion Within theslot, so that both of these members will be free to rise, either intolockset position, or into knuckle-throwing position. The forwardmovement of the member 10 is limited by a stop 13, at the lower end ofthe lifting rod, and its rearward movement is limited by an intermediatestop 14, on the lifting rod, in the rear portion of the slot, whichengages the upper end of the link member. The projection 7 on the bentupper portion of the rod engages the hook or eye 6, when the lock islifted, thus avoiding friction between the rear surface of the lock andthe vertical portion of the lifting rod. The lifting rod 8 and the linkmember 10, though made as separate pieces, are functionally united, inlifting the look, while having motion relative to each other in lockingthe lock, thus giving an advantage in simplicity and efficiency.

In the form shown in Figs. 3 and 4, the construction is similar to thatof Figs. 1 and 2, except that instead of the uncoupling rod 12, I employa longitudinally extended uncoupling lever 16, whose rear end is pivotedat 17, to the coupler shank, while its forward end is hooked through theeye 11 of the link member 10. This uncoupling lever is operated by anuncoupling rod 18, which extends beneath lever 16, in the form of acrank. When this crank is rotated on its axis, it raises the lever 16and operates the members 8 and 10.

The advantages of my invention result from the simplicity andcompactness of the coupler and opening device in the bottomopenlngcoupler.

Many changes may be made in the form and arrangement of the couplerknuckle, the locking and opening piece, and the opening members, withinthe scope of my claim.

I- claim:

A coupler having a swinging knuckle and a look, a stop on the couplerhead to prevent the look from creeping, alock-lifting memtending portionfor engagement with the her movable through the floor of the coupler,actuating means. 1 'an anti-creeper member pivoted to the lock- 'Intestimony whereof, I have hereunto set lifting member in its lowerportion and havmy hand.
